Thank you, Shubham.

Well, another question is, I got the error message :  "An error has occurred
when activating this view, java.lang.NullPointerException"

I can see the Operator Graph is working, but when I run the pig or hadoop
(by pressing the pig or hadoop icons), this error message comes out.
 Something wrong with an array?  Please help.  Thank you.

One minor question maybe more about Eclipse.  I didn't find the red button
to stop a query running.  Do you know how to stop it?  Thank you!

When I got the error message  "An error has occurred when activating this
view, java.lang.NullPointerException" ,
On my console is:

Connected to map-reduce job tracker at: localhost:9001Connected to hadoop
file system at: hdfs://localhost:9000/
Connected to map-reduce job tracker at: localhost:9001
Connected to hadoop file system at: hdfs://localhost:9000/

and there is nothing shown on "Pig Example Window ",

On the "Progress" is "Synchronizing Task Lists (Sleeping)"
Why sleeping? Is that the reason for a NullPointerException  on Task Lists?


Thank you!
